Warning /Alarm 9 in VLT Micro Drive FC301/ FC302 : Inverter overloaded - the drive has run with more than 100% overload for too long and is about to cut out. The counter for electronic thermal inverter protection issues a warning at 98% and trips at 100% with an alarm. The drive cannot be reset until the counter is below 90%.
